  • How to stream from camera to browser using ffmpeg [closed]

    7 juin, par Gabriel Furstenheim

    FFMpeg just merged support for WebRTC.

    


    If I understand correctly, this should allow to stream directly from ffmpeg to a website without the use of a server.

    


    How does this work ?

    


    ffmpeg -f dshow -i video=MyCamera ???


    


    I guess something similar to

    


    I'm guessing something like

    


    ffmpeg -f dshow -i video=MyCamera -f webrtc udp://localhost:6666


    


    Also, how would the website look like ?

    


    For simplicity, assume that everything happens in localhost

  • How to fix av_interleaved_write_frame() broken pipe error in php

    31 mars, par Adekunle Adeyeye

    I have an issue using ffmpeg to stream audio and parse to google cloud speech to text in PHP.

    


    It returns this output.
I have tried delaying some part of the script, that did not solve it.
I have also checked for similar questions. however, they are mostly in python and none of the solutions actually work for this.

    I'm not sure what the issue is at this time.

    I've done some more debugging and i have gotten the error to clear and to stream actually starts.
